[Bug 342923] Re: (Needs UXA) Kubuntu Jaunty Intel 945 GM - Poor sluggish graphics performance in Kate text, etc.

This does not solve the issue for me. With effects off I still get terrible screen refresh noticeable most when switching desktops and when scrolling in apps like Firefox.

Not possible on my system. Enabling UXA causes the X server to crash when trying to load so can't even get to a kdm logon screen.

I also tried these options but they caused major visual corruption when trying to enable a 2nd monitor using xrandr after logon. 

Whilst I understand the sentiment that the priority is a working desktop
rather than performance, the speed this reduces a system to make it
practically unusable as an everyday environment. Similar to others
above, I was running KDE 4.2 under Intrepid and had no such issues, so
this is likely a problem between kwin and the newer intel driver.
